1. **Potential for Misalignment**

- Some users complain that the **grease fittings** are not as robust as OEM parts, leading to premature failure.

3. **Limited Customization**

- The Mevotech 508MA63 is a **standard-length replacement** and does not offer adjustable lengths (unlike some high-end performance parts).
